Here's a silly question: are you not able to update
the code on your system control computer such that the
default state for the two problematic UHF transponders
is off rather than on?
I'm sure you already considered it but I thought I'd
ask because I'm very curious.

Today, 29 Nov, PCsat is 50% (6 days) through
its 12 day full-sun period. In fact, today, PCsat's
orbit flies almost perfectly over the day/night
line so you you get about equal passes in the
hour before and after sun rise and sunset.
On http://pcsat.aprs.org, I notice about 45 users
today, and about 72 different calls in the last
2 days.
In 6 days, when PCsat returns to eclipses,
we are usually lucky enough to keep
her from resetting for a few more weeks and
at least daylight operations can continue
normally. But once it resets, either due to
peak user load or an SEU, then we lose her
again until the next full sun period in the
first week of March 2006.
PCSAT2 should come back to life on the 1st
of Dec and so we should get some time for
joint dual-hop experiments.
